We wanted to assess the number of unnecessary radiographs done for acute knee injury patients and the accuracy of the Pittsburgh decision rules.
A retrospective observational study was done to look at the acute knee injury patients presented to a district general hospital Accident and Emergency Department from August 2011 till August 2013. We assessed the following parameters: sex, age, mechanism of injury, weight-bearing status and incidence of fractures in patients subjected to plain radiograph. A prospective study was then done from April 2014- August 2014 following implementation of the Pittsburgh decision rules.
24% of the patients had knee X-ray, compared to 72.12% in the first cycle. 36.8% had fracture, compared to 6.1% first cycle, with 66.7 % reduction in x-rays. Pittsburgh decision rules sensitivity was 100% and specificity 85.3%, positive predictive value 45.8% and accuracy 87%.
我们想要评估急性膝关节损伤患者进行不必要X光检查的数量以及匹兹堡决策规则的准确性。
开展一项回顾性观察研究，观察2011年8月至2013年8月在一家地区综合医院急诊科就诊的急性膝关节损伤患者。我们评估了以下参数：患者的性别、年龄、损伤机制、负重状态以及接受X光检查患者的骨折发生率。在实施匹兹堡决策规则后，于2014年4月至2014年8月进行了一项前瞻性研究。
24%的患者进行了膝关节X光检查，而在第一个周期这一比例为72.12%。36.8%的患者发生骨折，第一个周期为6.1%，X光检查减少了66.7%。匹兹堡决策规则的敏感性为100%，特异性为85.3%，阳性预测值为45.8%，准确性为87%。
